dt-bindings: can: convert microchip,mcp251x.txt to yaml

Convert binding doc microchip,mcp251x.txt to yaml.
Additional change:
- add ref to spi-peripheral-props.yaml

Fix below warning:
arch/arm64/boot/dts/freescale/imx8dx-colibri-eval-v3.dtb: /bus@5a000000/spi@5a020000/can@0:
	failed to match any schema with compatible: ['microchip,mcp2515']

* Microchip MCP251X stand-alone CAN controller device tree bindings
Required properties:
- compatible: Should be one of the following:
- "microchip,mcp2510" for MCP2510.
- "microchip,mcp2515" for MCP2515.
- "microchip,mcp25625" for MCP25625.
- reg: SPI chip select.
- clocks: The clock feeding the CAN controller.
- interrupts: Should contain IRQ line for the CAN controller.
Optional properties:
- vdd-supply: Regulator that powers the CAN controller.
- xceiver-supply: Regulator that powers the CAN transceiver.
- gpio-controller: Indicates this device is a GPIO controller.
- #gpio-cells: Should be two. The first cell is the pin number and
the second cell is used to specify the gpio polarity.
Example:
can0: can@1 {
compatible = "microchip,mcp2515";
reg = <1>;
clocks = <&clk24m>;
interrupt-parent = <&gpio4>;
interrupts = <13 IRQ_TYPE_LEVEL_LOW>;
vdd-supply = <&reg5v0>;
xceiver-supply = <&reg5v0>;
gpio-controller;
#gpio-cells = <2>;
};
